Hi there, public transport does not currently come past our gate, though you could arrange a taxi from Port Chalmers which is 15 minutes away. Thank you from the team at Orokonui
There's not really public transportation to this place, though the intercity bus lines might drop and pick-up there. If you are planning to stay in Dunedin, a tour company like:
exploring net nz
would be a good option. They have a tour package that picks you up in downtown Dunedin and runs out to the sanctuary, with some other stops along the way. It's about half an hour out of Dunedin if one were to drive straight there.
